Ubuntu 18.04 intel wireless ac 9260 "This device is not working" under additional drivers, but wifi is working

Question

I just did a fresh 18.04 install. Now my wifi isn't recognized for some reason, but I'm using wifi right now. I'm not sure what this means here's a screenshot of it.

I tried some possible solutions here, but they didn't work for me. I also have windows 10 installed on the same laptop, but on another drive entirely. Also, worth mentioning is that I had Ubuntu 18.04 installed previous on the same laptop and I didn't have this problem before. Only after I tried doing a fresh install for the 3rd time (don't ask, I'm still learning) than I run into this issue.

I don't know if this is important, but after the install my system time was off by like 5hrs after I set the right time zones and everything. I had to go into bios and change the time and disable the automatic date & time settings for Ubuntu. Otherwise I wasn't even able to run Ubuntu updates because the time didn't match with the ubuntu servers. Anyway...

Here are some system specs:

According to the solution here it's ok to leave it as is, but I'm not entirely sure because as I mentioned before I had ubuntu working fine before and only after a fresh install I ran into this problem. I would appreciate any help with this. I'm at a loss here, thank you.

It is OK to leave it as is. If your wireless is working correctly, there is no need to do anything at all. — chili555, Jan 16 '20 at 23:45
yeah, it's working for now, but it doesn't make any sense why it says This device isn't working. — Pachuca, Jan 17 '20 at 03:34
it could be, but why didn't it show up originally? I never had this display in additional drivers tab before. The only thing that changed is that I did a reinstall of ubuntu. I've tried all of the install versions from 18.04.1 to 18.04.3 and I get the same thing. The only other thing I could think of is maybe there was a recent windows up date that is conflicting things in my system because I also run windows on a separate drive inside the same laptop, but I physically removed that drive and boot into ubuntu without any change in the additional drivers tab so idk... — Pachuca, Jan 30 '20 at 04:45

Mystery found, but not solved. This appears to be a bug. If anyone else is having this problem, check it out at that link.

software-properties-gtk erroneously reports that certain Intel wireless adapter cards are not working
Bug #1859308 reported by Naël on 2020-01-12
Bug Description
On Ubuntu 20.04 (development branch), as of today, Additional Drivers (software-properties-gtk 0.98.6) reports that the device "Intel Corporation: Wireless-AC 9260" is not working, and suggests using a manually installed driver (cf. screenshot).
However the device is working correctly:

lsmod | grep iwlwifi, lspci -v, lshw, dmesg | grep iwlwifi all show
that its driver iwlwifi is in use
ls /lib/firmware/9260 show that the appropriate firmware files
are present

And I am indeed writing this bug report connected to an ac (5 GHz) wifi network, where I can verify a ~130-160 Mbps download speed, so software-properties-gtk shouldn't report the device as not working and suggest manually installing a driver. Not sure why it says so?
EDIT: bug confirmed as affecting the following Intel wireless adapter cards, and assumedly more to come:
Intel Wi-Fi 6 AX200
  Intel Dual Band Wireless-AC 3165
  Intel Dual Band Wireless-AC 7260
  Intel Dual Band Wireless-AC 8260
  Intel Wireless-AC 9260

That link appears to be broken - can you please update the question with a working link and ideally some info that doesn't rely on a link? — Ross, Apr 02 '20 at 17:17
@Ross the link is working. I added the bug description also. — Pachuca, Mar 23 '22 at 04:39
